IJCWidgetCookie (Instant JChem Core API)

All Superinterfaces:

org.openide.nodes.Node.Cookie
```
public interface IJCWidgetCookie
extends org.openide.nodes.Node.Cookie
```
This cookie is used for identification of selected widget in view (grid/form) and manipulation with the data and state (navigation, sorting, add/remove rows and columns, etc.)
Use utilities methods to compute common DFResultSet.VertexState or union of DFFields for all selected IJCWidgets. The utility methods are available in IJCCoreUtils.
